TUBULAR DESPAT C H APPARATUS.

SPECIFICATION forming part of Letters Patent No. 669,886, dated March 12, 1901.

Application filed July 10, 1900.

l the general class of tubular transit systems in which fluid underpressure or suction is utilized as a motive force; and the present improvements relate particularly to apparatus for ascertaining the position of and moving carriers in such tubes without removing such pressure or suction therefrom; and it consists of sight-indicators and moving levers applied to such tubes at points where such ascertainment and movement is'requisite.

- This invention is particularly applicable tothe tube adjacent. switches, gates, valves, transmitters, receivers, and all points upon a tubular transit-line where carriers are likely to stick, jam, or block and where their position is required to be located and such carrier or carriers moved forward, backward, or away from such obstruction or point; and the production of a compact and convenient de-. vice to accomplish such ascertainment or movement constitutes the object of this invention. I attain this object by the mech anism illustrated in the accompanying drawings, in which- '.-I

Figure 1 is a side elevational view of a section of transit-pipe adjacent a gate with my invention applied thereto; Fig. '2, a horizontal-section on line X X of Fig. 1, showing my device normally at rest; and Fig. 3, a similar view showing my device in position for movmg a carrier.

Similar numerals designatesimilar parts throughoutthe several views.

Referring to the drawings, 1 represents a. section of transit-pipe; 2, a gate therein; 3, a chest forming part of said pipe; 4, a similar oppositely-disposed chest; 5 6, plates of glass or othertransparent material mounted in said chest; 7, a stuffing-box upon one end of chest 3; 8, a'shaft mounted in said stuffing-box and through glass 5 in chest 3.

capable of rotary and longitudinal movement therein; 9, an arm integral with theinner end of said shaft; 10, a lever fixed to the outer end of said shaft, and 11 a carrier resting within the tube, 1.

The operation is as follows: We will su pose that a carrier is jammed in the halfclosed gate 2 and it is desired to withdraw said carrier fi om under the gate against the pressure to allowthe gate to close. The position of the carrier is first ascertained by applying light, if the ordinary light is not sulficient, to theglass 6 in chest- 4 position of the carrier is ascertained, the shaft 8 is drawn out or pushed in until the arm 9 is in such a position that when rotated it will engage a packing-ring, similar part, or end of 'the.carrier.' Then the shaft is rotated by hand-lever'lO until arm 9 engages the carrier and is pushed in or pulled out, as the case may require, carrying the carrier with it, the gate being previously raised to permit the carrier to clear the same. N

When theshaft or levers are not ih use, the weight of lever 10 carries the arm 9 into the chest 3 and out of the passage of the carriers.

-W hen the exact,

and glancing It is obvious that various changes may be made in. the details, construction, and appli: cation of thisdevice without departing from the spirit of my invention.

Having now described my invention, what I claim, and desire to secure cut, is-

1. In combination with a tubular transitpipe, a carrier-moving mechanism, substantially as and for the purpose set fortln.

2. In combination with a tubular transitpipe, an enlarged portion thereof, a shaft journaled therein and capable of rotaryand longitudinal movement, a lug upon one end vof said shaft andgmeans upon the other end for rotating and moving said shaft, substantially as described.

. 3. Iucornbination with a tubular transitpipe, an enlarged portion thereof, a stuffing- .boxtherein, and a shaft journaled in said stufling-box parallel to said transit-pipe and capable of rotary and longitudinal movement, alug upon the innerend of said shaft adapted to enter said transit-pipe upon the rotation of by Letters Pattoo .4. In combination with a tubular transitpipe, at sighti-indicator'and a carrier-moving lever, substantially as and for the purpose set forth. 7

5. In combination with a tubular transit- I pipe,oppositely-d a carrier-moving isposed sight-indicators and lever capable of rotary and longitudinal movement, substantially as and for the purpose set forth.

i In testimony whereof I have signed my name to this specification in the presence of two subscribingwitnesses WASHINGTON A. H. BOGARDUS.
